The upper connection member is provided at a bar-shaped connection bar and both ends of the connection bar, respectively, and is engaged with the upper end portion of the support column. A locking bracket that is stopped, and the locking bracket includes an upper plate portion that protrudes in an axial direction of the connection bar from an end portion of the connection bar along an upper surface of the connection bar, and the upper plate portion. The end face of the connecting bar from the tip of the And the upper connecting member is configured such that the insertion piece abuts against an inner peripheral surface of the support column, and an end surface of the connection bar is an outer peripheral surface of the support column. In the state where it hits, the projection is locked to the upper end portion of the support column, and a protrusion projecting toward the inner peripheral surface is formed on the insertion piece on the side facing the inner peripheral surface of the support column, A hole or a recess into which the protrusion is fitted is formed on the inner peripheral surface of the support column, and the cap is inserted in a direction away from the inner peripheral surface of the support column, which is a direction in which the protrusion is pulled out from the hole or the recess. It has a side plate that restrains the displacement of the piece.
In this way, the insertion piece and the end face of the connecting bar are sandwiched between the inner peripheral surface side and the outer peripheral surface side, and further, the cap restrains the displacement of the insertion piece in a direction away from the inner peripheral surface of the support column. By doing so, the upper connecting member can be firmly connected to the upper end of the support column.

  Furthermore, since the cap restrains the displacement of the insertion piece in the direction away from the inner peripheral surface of the support column, the protrusion can be prevented from coming out of the recess, and the connection strength of the upper connecting material to the upper end portion of the support column can be further increased. Enhanced.

  In addition, a protrusion 30 that protrudes toward the end face 20f is formed on the insertion piece 23 at a position facing the lower end 20f1 of the end face 20f of the connecting bar 20 by pressing.

As shown in FIG. 5, such a locking metal fitting 21 is formed by bending a plate material 25 obtained by stamping a steel plate into a predetermined shape by pressing so that the upper plate portion 22 and the insertion piece 23 are substantially L-shaped. Formed. Here, when the upper plate portion 22 and the insertion piece 23 are normally bent into an L shape by bending, the surface 22f and the surface 23f on the side facing the connecting bar 20 form an R shape at the bent portion L. On the other hand, in the present embodiment, as shown in FIG. 5C, the surfaces 22f and 23f on the side facing the connecting bar 20 in the upper plate portion 22 and the insertion piece 23 of the locking fitting 21 are bent portions. In L, a right angle portion 26 is formed.
For this purpose, as shown in FIGS. 5A and 5B, a groove 27 having a V-shaped cross section is formed in a plate material 25 punched out in a predetermined shape by a punch 100 of a press.
Next, as shown in FIG. 5C, the punch 100 is again applied to the groove 27 of the plate material 25 and pressed with the die 101 to be bent. As a result, the upper plate portion 22 and the insertion piece 23 are bent in an L shape, and a right angle portion 26 is formed in the bent portion L.

  As shown in FIG. 4, a guide plate 29 that protrudes in the axial direction of the connecting bar 20 from the end face 20 f is formed on the connecting bar 20 on the side along the upper plate portion 22 of the locking fitting 21. The guide plate 29 has a tip surface 29 f formed in parallel with the end surface 20 f of the connecting bar 20. The guide plate 29 has a projecting dimension from the end face 20 f that is the same as the distance c between the insertion piece 23 and the end face 20 f of the connecting bar 20.

Now, as shown in FIG. 3, each of the locking grooves 17 </ b> B formed in the upper end portion of the support column 12 has a width W <b> 5 into which the wide plate portion 22 d of the upper plate portion 22 of the locking bracket 21 can be inserted. . Here, although the width W5 of the locking groove 17B is larger than the width W2 of the wide plate portion 22d, it is preferable to make it as small as possible so that the locking metal fitting 21 does not rattle in the width direction in the locking groove 17B.
The depth d of the locking groove 17B is set to be approximately the same as the thickness t of the upper plate portion 22. The greater the depth d of the locking groove 17B, the lower the rigidity at the upper end of the support column 12, so it is preferable to make it as small as possible.

  Through holes (holes) 31 are formed in the side surfaces 12a and 12b of the support column 12 at positions below the locking grooves 17B. The through hole 31 is formed such that the distance from the locking groove 17B is equal to the distance from the surface 22f of the upper plate portion 22 of the locking bracket 21 to the protrusion 30.

In the configuration as described above, in order to connect the upper connecting member 14 to the upper end portion of the column 12, as shown in FIG. 3, the insertion pieces 23 of the locking metal fittings 21 at both ends thereof are arranged in the axial direction of the column 12. It inserts in the support | pillar 12 along. At this time, the side surfaces 12 a and 12 b of the support column 12 are inserted into a gap between the insertion piece 23 and the end surface 20 f of the connecting bar 20.
At this time, the protrusion 30 formed on the insertion piece 23 abuts against the inner peripheral surface 12 i of the side surface 12 b of the support column 12, whereby the insertion piece 23 is elastically deformed to the side away from the end face 20 f of the connecting bar 20. When this insertion operation is continued, the surface 22f of the upper plate portion 22 of the locking fitting 21 comes into contact with the upper surface of the side surface 12b of the support column 12. Then, the protrusion 30 is fitted into the through hole 31.

  In this state, as shown in FIG. 6, in the locking fitting 21 of the upper connecting member 14, the insertion piece 23 hits the inner peripheral surface 12 i of the side surfaces 12 a and 12 b of the support column 12, and the end surface 20 f of the connecting bar 20 is the support column 12. Of the side surfaces 12a and 12b of the outer peripheral surface 12h, and contact the surface. As a result, the side surfaces 12 a and 12 b of the support column 12 are sandwiched between the insertion piece 23 and the end surface 20 f of the connecting bar 20.

As shown in FIGS. 3 and 7, a cap 60 is attached to the opening at the upper end of the column 12 to which the locking fitting 21 of the upper connecting member 14 is locked in this way.
3, 6, and 8, the cap 60 includes a cover plate portion 61 that is formed to have substantially the same outer dimensions as the cross-sectional view of the support column 12, and a surface 61 a from the cover plate portion 61. And an insertion portion 62 that is inserted into the support column 12 and is formed integrally. As a result, the cover plate portion 61 is formed so as to protrude outward from the insertion portion 62.

  The insertion portion 62 includes side plates 63 and 63 which are formed in positions facing the side surfaces 12a and 12b when they are inserted into the internal space of the support column 12, and are parallel to each other. The cross section is substantially H-shaped, and includes a connecting portion 64 that is connected at a middle portion in the direction.

  In each side plate 63, a groove continuous in a direction orthogonal to the surface 61 a of the cover plate portion 61 on the side facing the outer periphery in the insertion portion 62 (the side facing the inner peripheral surface 12 i of the side surfaces 12 a and 12 b of the support column 12). 65 is formed. The groove 65 has a width W6 that is larger than the width W2 of the insertion piece 23 so that the insertion piece 23 of the locking fitting 21 can be accommodated.

  In the groove 65, the groove bottom surface 65 a on the side facing the outer periphery of the insertion portion 62 (the side facing the inner peripheral surface 12 i of the side surfaces 12 a and 12 b of the support column 12) extends in a direction orthogonal to the surface 61 a of the cover plate portion 61. Two protrusions (pressing portions) 66, 66 are formed to protrude in the width direction of the groove 65 with an interval.

  Further, in the side plate 63, a ridge 68 extending in a direction orthogonal to the cover plate portion 61 is formed to protrude on a side surface 63a orthogonal to the groove bottom surface 65a.

As shown in FIG. 6, such a cap 60 is attached to the opening of the upper end portion of the support column 12 by inserting the insertion portion 62 into the internal space of the support column 12. At this time, rattling of the insertion portion 62 in the column 12 is suppressed by the protrusion 68 formed on the side plate 63.
The side plate 63 is formed to extend below the protrusion 30 formed on the insertion piece 23 in a state where the cover plate portion 61 is in contact with the upper surface of the support column 12. As a result, almost the entire insertion piece 23 is pressed from the inside by the side plate 63.

In the insertion portion 62 inserted into the internal space of the column 12, the insertion piece 23 is accommodated in the groove 65 of the side plate 63. At this time, the insertion piece 23 is pressed to the inner peripheral surface 12 i side of the column 12 by the protrusions 66, 66 formed on the groove bottom surface 65 a of the groove 65. Thereby, in a state in which the protrusion 30 formed on the insertion piece 23 is fitted in the through hole 31 of the side surfaces 12a and 12b of the support column 12, the direction in which the protrusion 30 comes out of the through hole 31 (the direction away from the inner peripheral surface 12i side). ) To restrain the insertion piece 23 from being deformed. Moreover, the side plate 63 is restrained from being deformed by the connecting portion 64 in a direction away from the side surface 12 a of the support column 12.
In this way, the cap 60 prevents the protrusion 30 of the insertion piece 23 from coming out of the through hole 31, thereby preventing the connection of the upper connecting member 14 to the column 12 from being inadvertently released. .

  In this way, as shown in FIG. 7, the upper connecting member 14 is connected between the upper ends of the columns 12 and 12 when the cap 60 is fitted into the column 12.

According to the configuration as described above, the upper connecting member 14 has the insertion piece 23 that abuts against the inner peripheral surface 12 i of the support column 12 and the end surface 20 f of the connection bar 20 contacts the outer peripheral surface 12 h of the support column 12. And the end surface 20f of the connecting bar 20 are locked to the support column 12 with the side surfaces 12a and 12b of the support column 12 being sandwiched. At this time, since the distance between the end surface 20f of the connecting bar 20 and the insertion piece 23 corresponds to the thickness of the material forming the side surfaces 12a and 12b of the support column 12, the back connection between the upper connection member 14 and the support column 12 occurs. Is suppressed.
Further, the protrusion 30 provided on the insertion piece 23 is fitted into the through hole 31 formed in the side surfaces 12a and 12b.
In addition, the insertion piece 23 is pressed against the inner peripheral surface 12 i of the support column 12 by the side plate 63 of the cap 60 inserted into the internal space of the support column 12, and the direction in which the fitting between the protrusion 30 and the through hole 31 is released ( The insertion piece 23 is restrained from being deformed in the direction away from the inner peripheral surface 12i.
In this way, even when a lateral external force is applied due to a strong earthquake or the like, it is possible to reliably prevent the locking fitting 21 from coming off from the upper end portion of the column 12. As a result, the earthquake resistance of the article display shelf 10 can be improved.
Moreover, the upper connecting member 14 only needs to be fitted with the cap 60 after being fitted into the support column 12 from above, and the assembly work can be easily performed.

Further, the locking metal fitting 21 is inserted into the end face 20f of the connecting bar 20 by providing the guide plate 29 at the end 20a of the connecting bar 20 while forming the upper plate portion 22 and the insertion piece 23 by bending. The interval with the piece 23 is formed with high accuracy.
Further, by forming a groove 27 having a V-shaped cross section in the bent portion L of the upper plate portion 22 and the insertion piece 23, a right angle portion 26 is formed in the bent portion L after the bending process. Yes. As a result, the guide plate 29 abuts against the bent portion L without a gap, so that the gap between the end face 20f of the connecting bar 20 and the insertion piece 23 can be formed with high accuracy.
